12 1/4 IADC637 Metal Seal Roller Bit
1.Using high-strength and high-toughness cemented carbide teeth to improve the impact resistance of the teeth and reduce the rate of broken teeth;
- The optimized design of the number of teeth rows, the number of teeth, the height of the exposed teeth and the unique alloy tooth profile make full use of the cutting ability and speed of the drill;
- The spring is used to lock the cone, which can withstand high drilling pressure.
- The inner hole of the cone is welded with anti-wear alloy to improve the anti-seizure ability of the bearing;
- The use of high-saturated nitrile rubber O-rings, the optimized seal compression increases the reliability of the bearing seal;
- The all-rubber oil storage bag that can limit the pressure difference and prevent drilling fluid from entering the lubrication system, provides good lubrication for the bearing system, and ensures the normal operation of the “O” -shaped seal ring, which increases the working life of the drill bit;
- The new type of grease with high temperature and low temperature resistance of 250 ℃ is adopted to improve the high temperature resistance of the drill bit seal lubrication system.
- High wear-resistant alloy sand is used to harden the entire surface of the palm back and teeth, thereby greatly improving the service life of the drill.
- Optimized design of the number of rows of teeth, the number of teeth, the height of the exposed teeth and the unique profile of the teeth, giving full play to the cutting ability and speed of the drill;
3. The main diameters are: 4 5/8 “, 6”, 7 “, 7 1/2”, 8 1/2 “, 9 1/2”, 9 5/8 “, 9 7/8”, 12 1 / 4 “, 12 1/2”, 14 3/4 “, 15”, 15 1/2 “, 16”, 17 1/2 “, 22”, 26 “, etc.
4. Steel tooth cone bit is suitable for soft formations, soft to medium hardness formations, and is widely used in oil field, mining, geological survey, hydrological exploration, engineering piling, geothermal development, water wells and other drilling fields.
Our company can provide specific solutions according to the actual drilling conditions, and customize any diameter assembly drill bits, including large-diameter pile foundation drill bits, different types of drill bits, reaming drill bits, directional well drill bits, etc.
